Siaon Optoelectronic provide a series of precision optical components

Polarizing Cube Beamsplitters split randomly polarized beams into two orthogonal,linearly, polarized components-S-polarizedlight is reflected at a 90deg. Angle while P-polarized light is transmitted. Each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of prisms.
